The 318i is a 4 cyl engine. The only way their would be a 6 cyl engine is if someone did an engine swap. All 6 cyl BMW engines are Inline 6 engines, not V6's. I could tell you what motor was in it if you are able to post a picture.

It is possible that the dash lights for those indicators were removed or disabled. Take the car to an auto parts store or mechanic and have them scan the OBD system for Codes. If their is a warning light that is supposed to illuminate the computer would have "thrown a code" as its called. To see if the lights were removed you can remove the instrument cluster.

how to post pic ? ......
